The preparation method of the modified bamboo charcoal powder includes adding epoxy soybean oil with the weight amounting to 1-2% of that of bamboo charcoal, silane coupling agent KH 792 with the weight amounting to 1-2% of that of the bamboo charcoal, Span-80 with the weight amounting to that of the bamboo charcoal and appropriate amount of water into the bamboo charcoal; after mixing the mixture at 35-40 DEG C for 20-30 minutes, taking the mixture out and putting the mixture into sodium chloride solution with a concentration of 8-9% for soaking for 10-14 hours; taking out and drying the mixture to obtain the modified bamboo charcoal powder.

Description

A kind of waterproof thermal insulation mortar

Technical field

The present invention relates to the thermal insulation mortar field, is exactly a kind of waterproof thermal insulation mortar.

Background technology

Thermal insulation mortar is take various light materials as aggregate, take cement as gelating material, admixes some property-modifying additives, mixes and a kind of premixing dry-mix of making through manufacturing enterprise.Be mainly used in building exterior wall heat preserving, have the advantages such as easy construction, good endurance.

Summary of the invention

The object of the present invention is to provide a kind of waterproof thermal insulation mortar.

Above-mentioned purpose realizes by following scheme:

A kind of waterproof thermal insulation mortar is characterized in that: it is that raw material by following weight parts makes: ordinary Portland cement 200-300, sugared calcium 10-14, glass bead aggregate 30-40, white glue with vinyl 10-20, trevira 1-2, modified bamboo powdered carbon 8-12, sodium lignosulfonate 0.5-0.7, trolamine 0.4-0.8, lime acetate 0.3-0.6, gypsum 12-14, sodium laurylsulfonate 0.1-0.2, capillary crystalline waterproofing agent 0.3-0.5, water is appropriate; The preparation method of described modified bamboo powdered carbon is: will add the epoxy soybean oil that is equivalent to its weight 1-2%, the silane coupling agent KH792 of 1-2% in bamboo charcoal powder, the Span-80 of 0.1-0.2% and appropriate water, after stirring 20-30 minute under 35-40 ℃, take out, the sodium chloride solution of putting into concentration again and be 8-9% soaked 10-14 hour, take out, oven dry, and get final product.

Described a kind of waterproof thermal insulation mortar is characterized in that:

The preparation method is:

(1) with sodium lignosulfonate, trolamine, lime acetate, sodium laurylsulfonate mixing by weight, then add and be equivalent to above-mentioned raw materials gross weight 3-4 water doubly, stirred 10-20 minute under 20-25 ℃, get cement adding liquid standby;

(2) with cement and cement adding liquid mixing, under room temperature, stirred 20-30 minute under 100-200 rev/min;

(3) add by weight more sugared calcium, white glue with vinyl, capillary crystalline waterproofing agent, under room temperature, stirred 10-20 minute under 100-200 rev/min;

(4) add again surplus stock, stirred 10-14 minute under 100-200 rev/min, and get final product.

Beneficial effect of the present invention is: the present invention is composite by adding various cement additires and capillary crystalline waterproofing agent, has solved the large problem of traditional thermal insulation mortar water-intake rate, and water resistance is excellent.
